TRUCK.

V Toall whom it may concern;

' Be it known that .I, lViLLIAM G. Maren, a citizen of the UnitedStates, and a resident of Pittsburgh, in the county of Allegheny andState of Pennsylvania, have invented a new and useful Improvement inTrucks; and I-do herebydeclare the follow ing to be .aifull, clear; andexact description thereof. i

' This invention relates, to vehicles, and more particularly to vehicleshaving dumping bodies, and has for its particular ob ect the arrangementofa hand operated mechanisnrfor dumping thebody.

Another and important object. is the arrangement of the dumpingmechanism so that both a pulling and lifting-operationoccurssimultaneously, thereby facilitating the raising'of thebody, v 7

A still furtherobject isto provide an endgate that maybe hinged at thetop or bottom, as desired, and to-provide automatic closing mechanismtherefor when hinged at the top;

Various other objects, such as simplicity, durability, cheapnessinmanufacture, and the general improvement of the-art, willbe broughtout in the following specification and illustrated inthe accompanyingdraw.- ing, in which? l Figure 1 is a side elevation of a motor truckhaving the invention applied thereto and showing the body in dumpingposition; Fig. 2 is a front view of the body-"ofa truck showing thedumping mechanism;

Fig. 3 isa rear view showing the novel endgate construction;

rear edge of each sideis bound by a permanently secured metallic strip10 having a stripsli thereon,which have their ends bent upon' themselvesforming cylindrical rod re ceiving portions 15." Rods 16 pass throughand aresecured in the portions'l5 and are adapted to engage within theslots 11 in member ,rlOgfand to be held therein by pins 7 12. It will beunderstoodthat' rods 16 are adapted to be;locked in either the upper orlower slots 511 according to which way the end gate is to be openedismceby locking the rod 16 in the slots 11 a hinge connection is completed. 7V .A chain 17 is passed through the eyes 18 on the endgate and eyes 19onthelsides of the body B in the usual fashion to control the movementof the endgate. when it is hinged at the lower side."

The body portion B being pivotally mounted on the chassis at 6, asbefore de-; scribed, is adapted tobe raised into dumping position :bymeans "of a suitably arranged cable mechanism which causes a lift? ingaction on the'forward portion of the body and a pulling action on therear portion. a t

4 The raising mechanism'comprises a main shaft 20 journaled inv bracketbearings 21 and having a-large gear 22' secured on its one end; Astub-shaft 23 is journaled in one bearing and carries a power gear 24,and has its free end squared, at '25," for the reception of asuitableoperating crank 25.

A dog or stop ratchet 24 is mounted on the bearing bracket 21adjacentthe gear 22 and adapted to normally engage the same to preventits reverse movement.

A boom 26 is pivotally mounted on the bracket bearings at 27 and extendsupwardly and has a suitable pulley or sheave wheel 28 mounted at itsupper end.

A channel track portion 29 is secured on the front of the body portion Band is composed of two angle irons secured together and having theirlower. ends spaced apart, to form clearance for the double sheaves 31journaled in bearing 32 on the forward end of the body.

The boom 26 is adapted to ride upon the track 29 due to its pivotalmounting and to be guided by the side flanges thereto.

A second set of double sheaves 33 are journaled in bearing 34 secured onthe underside. of the rear end of the chassis in line with said firstdouble sheaves, and a single sheave 35 is journaled in bearing 36 on therear end of the underside of the body B.

A suitable drum 37 having its surface grooved as at 38 for the receptionof a cable 39 is mounted on the main shaft 20 and has one end of saidcable secured thereto.-

Cable 39 is trained upwardly from the drum- 37 over sheave 28 down andunder one side of the double sheave 31, back under one side of sheave33, up and around sheave 35, thence back under the other side of sheave33, and under the other side of sheave 31, thence upwardly to the eye 40secured in the boom 26, the end of the cable being secured to the eye40. i

Lever-arms 41 and 41 are pivotally connected by one end to lugs 42 and42 formed on strips 14 of the endgate and extend below the lower edge ofsuch endgate. Cables 43 and 43 are secured to. the free ends of thelever arms 41 and 41" respectively and are brought together and securedas at 44 then lead as one single cable forward and are secured as at 45to the cable 39 at a point on the return lap after such cable has passedaround the'sheave 35. The above combination of levers 41 and 41 andcables 42 and 42 are so arranged that whenthe body B is raised for duming the tensionof the cables will be release allowing the endgate toopen, and when the said body is lowered the cables will be tensionedthereby closing such gate. w

The operation of the device, in detail, is as follows 1 The completevehicle being assembled, and it being desired to dump a load from thebody B, the crank member 25 is placed in position on the squared end ofthe stubshaft 23; the crank is then turned driving the pinion 24 andlarge gear 22 on shaft 20. Drum 37 is secured on' shaft 20 and isconsequently rotated when such shaft rotates.

' As drum 37 is rotated cable 39 will be wound upon the same therebycausing a lifting action on the sheaves 31 due to such cable be ingdrawn over the pulley or sheave 28 on the boom 26. Simultaneously withthe lift-j ing action on the sheaves 31 the cable 39 will pull on thesheave 35 which is secured at the rear end of the-body portion B. By thecombined lifting and pulling action of the cables, the body B will berocked on its pivot6 so as to raise the front portion and placing thebody in inclined position.

, When used for dumping the endgate member 9 is hinged at its upper edgeto allow it to automatically swing outwardly at the bottom to dischargethe load from the body B when such body is raised in its inclinedposition. Cable members 43 and 43 are secured to lever arms 41 and 41hingedly secured to the endgate member 9 and extend forwardly and areengaged with the main operating cable 39 at'a point on its return looppast the sheaves 33. When the body portion B is raised the return-loopof the cable 39 moves rearwardly, thereby allowing the cables 43 and 43to move rear-wardly, permittingthe, endgate 9 to open to discharge theload from the body portion, and as the body I is lowered the return loopof the cable 39 will move forwardly and consequently cables 43 and 43will move forwardly thereby automatically closing the endgate 9 when thebody portion B is lowered.

It will be understood that when body portion B is to be used fordumping, the chain 17 will be either removed or hung very loosely .so asnot to interfere with the action of the endgate.

When it is desired to use the vehicle for ordinary hauling, suchasexpresswork, the

-endgate is hinged at the bottom by removing pins 12 and placing them inthe lower end of strips 10 thereby holding the lower rod 16 in thesockets 11 and releasing the upper rod 16. henthe endgate is hinged atthe bottom its movement is controlled by the chain 17 as in the ordinaryendgate construction, and such gate may be lowered 1. A vehicle of theclass described comprising a wheeled chassis, a body portion pivotallymounted on said chassis, a drum, a single cablesecured to said drum andsaid body portion, said cable being adapted to be wound upon said drumand combined to simultaneously exert a lifting action on the,

forward end and a downward pulling action on the rear end of said bodyto dump the same.
